The Dragino v2 was just released. This little device runs OpenWRT, supports wifi and mesh networking, and has remote flash of AVR (or Arduino) devices. The power consumption is rated at 1 watt…which is really good. This makes it feasible to run this from solar power.
This device has dropped to a great price point: $45. This makes it equivalent to a raspberry pi. It’s a nice price point to do home automation or remote DAQ.
Edit 12/23: The Dragino is now starting to show up Amazon Prime. This sounds a lot of effort arranging shipping from China,
